Each jar is designed to preserve your goods with its Ultraviolet properties that are built into the glass. UltraViolet Protection means you can leave your jar outside, in your kitchen or anywhere in your home without worrying about harmful light drying out your contents.
The jar only blocks out all damaging sunlight and only allows UV-A Light and Infra Red Light to pass through. These preserve your goods while blocking out harmful lights that damage and dry up any consumable items you store inside.
The jars dimensions are 4 inches by 3 inches, compact enough to fit on your counterop yet large enough to hold a half ounce of your favorite spices, herbs, coffees, teas and dried foods!
